Subject [jira] Created: (GERONIMO-515) GeronimoPolicyConfigurationFactory does not always return same instance

GeronimoPolicyConfigurationFactory does not always return same instance

         Key: GERONIMO-515
     Project: Apache Geronimo
        Type: Bug
  Components: security  
    Versions: 1.0-M3    
    Reporter: David Jencks

>From javadoc for getPolicyConfiguration(String contextID, boolean remove)

     * For a given value of policy context identifier, this method must always
     * return the same instance of PolicyConfiguration and there must be at
     * most one actual instance of a PolicyConfiguration with a given policy
     * context identifier (during a process context). <p>
     * To preserve the invariant that there be at most one PolicyConfiguration
     * object for a given policy context, it may be necessary for this method
     * to be thread safe.

>From our implementation:

        if (configuration == null || remove) {
            configuration = new PolicyConfigurationGeneric(contextID);
            configurations.put(contextID, configuration);
